Smart survey for TRL

Fugro Aperio collected and processed data from up to 7,000km lanes of English trunk roads as part of a just completed Traffic Speed Structural Survey (TRASS) contract. The work, commissioned by TRL on behalf of the Highways Agency (HA), saw the Cambridge-based survey specialist gain information using the HA’s Traffic Speed Deflectometer (TSD).

2929 Fugro Aperio collected and processed data from up to 7,000km lanes of English trunk roads as part of a just completed Traffic Speed Structural Survey (TRASS) contract.

The work, commissioned by 777 TRL on behalf of the 2309 Highways Agency (HA), saw the Cambridge-based survey specialist gain information using the HA’s Traffic Speed Deflectometer (TSD). The innovative TSD technology uses Doppler lasers to measure the speed at which the pavement deflects in response to load. The non-contact IT allows surveys to be conducted at up to 80kph, vastly reducing the risk to motorists caused by slower moving deflection techniques such as deflectograph and Falling Weight Deflectometer (FWD).

    When it comes to runways, there are few busier then Brisbane’s main runway. Servicing both domestic and international travel, with over 200,000 movements per year, operating without a curfew Brisbane’s main runway is the busiest in Australia. For maintenance, crews only have a limited period of time to determine the pavement condition, normally during the night, making the detection of pavement faults difficult. To resolve this issue, a new high speed pavement scanner was used to rapidly survey the pavem
